odness-of-fit test where all assumptions were met yielded the chi-square test statistic χ2=1.92 and a corresponding p-value of 0
mojhsa [17]

Answer: hello the options related to your question is missing attached below are the options

answer : The researcher did not state that the p-value is conditional on the null hypothesis being true ( A )

Step-by-step explanation:

What is wrong with the researcher's interpretation is that the researcher did not state that the p-value is conditional on the null hypothesis being true.

The P-value is a required value when either rejecting or accepting the null hypothesis. and the researcher did not add the clause that the probability of getting a statistic > 1.92 provided the null hypothesis is assumed to be true

A staircase is being constructed in a new house as displayed on the right. Each tread is 18 cm and each riser is 10cm. Determine
Verdich [7]

Answer:

29.1°

Step-by-step explanation:

Given that :

Riser, AB, Opposite = 10 cm

Thread, = AC, Adjacent = 18 cm

Angle of inclination, θ

Using trigonometry :

Tan θ = opposite / Adjacent = AB / AC

Tan θ = 10 / 18

θ = tan^-1(10/18)

θ = 29.055

Hence, angle of inclination is 29.1° (1 decimal place)

Find the y-coordinate of point M. the midpoint of AB, for A(-3,3) and B(5,7)
Rufina [12.5K]

The y-coordinate of the midpoint, M of the segment AB described by; A(-3,3) and B(5,7) is; 5.

<h3>What is the y-coordinate of the point M which is the midpoint of AB, defined by; A(-3,3) and B(5,7).</h3>

It follows from the task content that the y-coordinate of the midpoint, M of AB defined by; A(-3,3) and B(5,7) is to be determined.

Hence, it follows from coordinate geometry that the y-coordinate of the midpoint is such that;

y = (y(1) +y(2))/2

y = (3 + 7)/2

y = 5.

Ultimately, the y-coordinate of the midpoint of AB; A(-3,3) and B(5,7) is; y =5.

You have decided to cash in all of the coins you have been saving for the summer. In total you have $7.20. You only have dimes a
muminat

Answer:

The number of quarters in total = 16 quarters

The number dimes = 32 dimes

Step-by-step explanation:

The given information are;

The total amount of money in held = $7.20

The denomination of the money held = Dimes and quarters

The number dimes = 2 × The number of quarters

Given that a dime = 10 cents = $0.1

A dollar = 25 cents = $0.25

Let the number of quarters in the sum of money = X

Therefore, we have;

X × $0.25 + 2 × X × $0.1 = $7.20

X × $0.25 + X × $0.2 = $7.20

X × $0.45 = $7.20

X = $7.20/$0.45 = 16

Therefore, the number of quarters = 16

The number of quarters in total = 16 quarters

The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes

The number dimes = 32 dimes.
